Nordyne P3RC-036K Defrost Sensor Board
The defrost control board determines when to initiate the defrosting phase which actually helps to rid your unit of frost that can build up. The board is relayed information from a specific sensor located somewhere by the condenser to ascertain when to begin.
Signals your defrost board has very little life left
- The HVAC system control board might issue an error signal produced when the defrost board is bad
- The whole system may not operate at all because of the frost blocking the flow of air
- The defrost feature never kicks in despite the fact that there is a lot of frost that makes the unit run like crap
